Use a taper reamer to remove material from the outside of the brass. Turn the reamer clockwise to cut and counterclockwise to remove shavings. Rotate the piece frequently to prevent the tool from cutting into one spot.
Continue until the brass is slightly smaller in diameter than desired.
- 1) Using a lathe, cut the brass down to the desired diameter
- 2) Use a drill bit that is slightly smaller than the new diameter of the brass to create a pilot hole
- 3) Use a reamer to enlarge the pilot hole to the new diameter of the brass
Neck Down 308 to 7mm-08
Making 7Mm-08 Brass from 243
If you’re a reloader, there’s a good chance you have some 243 brass laying around. And if you’re like most reloaders, you’re always looking for ways to stretch your budget and get the most out of your brass. So why not make 7mm-08 brass from your 243 brass?
It’s easy to do and only requires a few simple tools. Here’s what you’ll need: -A set of Lee Collet Neck dies in 7mm-08 (or any other brand that will work with 243 Win brass)
-A small base sizer die in 7mm-08 (again, any brand will work) -A case trimmer designed for necked down cases like the Forster Original Case Trimmer -A drill bit slightly smaller than 7mm (.284″) or a reamer if you have one
-A chamfering tool -Some patience! First things first, resize your 243 brass using the small base sizer die.
This is important because it ensures that your cases will fit into the chamber of your rifle. Next, use the collet die to expand the necks of your cases. Be sure to lube them well first!
Once that’s done, it’s time to trim them down to length. The Forster trimmer makes this process quick and easy. Simply adjust it to trim your cases down to 2.035″, which is the standard length for 7mm-08 brass.
If you don’t have a Forster trimmer, you can use any case trimmer that will work with necked down cases – just be sure to adjust it properly so that you don’t end up with wonky looking cases! Now all that’s left is to chamfer and deburr the mouths of your newly minted 7mm-08 brass so that they’ll feed smoothly into your rifle’s chamber. And that’s it! You’ve now got quality 7mm-08 brass without spending a dime on new materials.
Is Neck Turning Brass Worth It?
There are a lot of opinions out there about neck turning brass. Some say it’s worth it, while others claim it’s not necessary. So, what’s the verdict?
Is neck turning brass worth it? The answer may depend on who you ask, but overall, the consensus seems to be that yes, neck turning brass is definitely worth it. Here’s why:
1. It extends the life of your brass. Neck turning removes any imperfections in the brass that could cause problems down the road. By taking care of these issues now, you’re prolonging the life of your brass and ensuring that it will continue to perform at its best for many reloads to come.
2. It improves accuracy. A properly turned neck will provide a more consistent release of the bullet, leading to improved accuracy. If you’re looking to tighten up your groups, neck turning is definitely worth considering.
3. It can save you money in the long run. While there is an initial investment required for the equipment needed to turn necks, over time this cost will be offset by the savings from extended brass life and improved accuracy (which means less wasted ammunition). In other words, neck turning can save you money in both the short and long term!
What is the Importance of Neck Turning?
Neck turning is an important process in reloading ammunition. It ensures that the bullet is properly aligned with the case neck, which in turn leads to more consistent accuracy and performance. When a case neck is not turned, it can cause the bullet to be misaligned when it is seated, which can lead to flyers (shots that are not as accurate as the others) and other consistency issues.
There are two main ways to turn a case neck: manually or using a power tool. Manual neck turning requires less investment up front, but it is a slower process. Power tools will speed up the process but they can be expensive.
Ultimately, the decision of how to turn case necks comes down to personal preference and what works best for each individual reloader.
Does Neck Sizing Improve Accuracy?
When it comes to reloading ammunition, there are a number of different factors that can affect accuracy. One of those factors is neck sizing. So, does neck sizing improve accuracy?
The answer is yes, neck sizing can improve accuracy. When you neck size a case, you are essentially ensuring that the case fits snugly around the bullet. This creates a better seal and results in less air turbulence when the bullet is fired.
Less air turbulence means more consistent shots and improved accuracy. Of course, there are other factors that also affect accuracy (such as barrel length, bullet weight, powder type, etc.), so neck sizing is not a guaranteed way to improve your accuracy. But it can certainly help and is definitely worth doing if you’re looking to get the most out of your reloads.
Are Neck Sizing Dies Better?
Are neck sizing dies better? This is a question that often arises among reloaders. The answer, like many things in reloading, is “it depends.”
There are several factors to consider when deciding whether or not to use a neck sizing die. The most important factor is what type of shooting you’ll be doing. If you’re only going to be shooting at paper targets, then neck sizing may not be necessary.
However, if you’re planning on hunting with your rifle or competing in long range matches, then neck sizing becomes much more important. Neck sizing helps to ensure that every round will fit into the chamber of your rifle without any issues. This is especially important when using factory ammunition, as it can often be slightly oversized.
Neck sizing also helps to prolong the life of your brass cases by preventing them from being resized too much. The downside of neck sizing is that it can sometimes make it more difficult to eject spent brass cases from your rifle. This isn’t usually an issue with bolt action rifles, but can be a problem with semi-automatic rifles.
Another potential downside is that if you ever need to resize your brass cases (for example, if you switch chambers), you may need to full length size them instead of just necksizing them. Ultimately, the decision of whether or not to use a neck sizing die comes down to personal preference and what type of shooting you’ll be doing. If you’re unsure, it’s always best to err on the side of caution and go with a neck sized die.

Once the brass is necked down, it can be used in a variety of rifles. This is a great way to save money on ammunition, as well as get more use out of your brass cases.
